Lidar measurements have not been listed, since they are still subject to algorithm intercomparison and evaluation in the frame of the NDSC.

The LAUTLOS database for different balloon-borne water vapor sensors flown in Sodankylä (Jan./Feb. 2004) will made publicly available 1 year after the campaign.
